OAKLAND, Calif. — One Goh's life was on the skids even before he became the suspect in the nation's biggest mass school shooting since Virginia Tech.
He was chased by creditors. He grieved the death of his brother. In January, he was expelled from Oikos University, a small Christian school where he studied nursing. And, police say, he was angry.
Goh, who was born in South Korea, told police he felt disrespected by teasing about his poor English skills at the Oakland school — a college founded as a safe place where Korean immigrants could adjust to a new country and build new careers.
So, he bought a gun and a few weeks later took his revenge, opening fire at the college on Monday in a rampage that left six students and a receptionist dead, and three more wounded, authorities said.
"It's very, very sad," police Chief Howard Jordan said. "We have seven people who didn't deserve to die and three others wounded because someone who couldn't deal with the pressures of life."
Police have released little background information about Goh, other than to say he had become a U.S. citizen. Since his arrest at a supermarket near the school soon after the shooting, the details of his life that have emerged suggest a man struggling to deal with personal and family difficulties over the past 10 years.
Records list an Oakland address for Goh in 2004, but he lived for most of the decade in Virginia, the site of the Virginia Tech massacre that killed 32 people in 2007. The gunman was a mentally ill student who shot himself.
Goh, now 43, spent a few months in late 2005 in suburban Richmond and three years in Gloucester County. In 2009, he was evicted for owing back rent. Online records in the two Virginia localities show that, while Goh was there, he racked up tens of thousands in liens and judgments, including a $10,377 debt to SunTrust Bank in 2006.
His brother was an Army sergeant stationed in Germany who died in a March 2011 car crash while attending training in Virginia, according to the military newspaper Stars and Stripes.
The same year, Goh's mother died in South Korea, where she had moved, her former Oakland neighbors told the San Francisco Chronicle.
It's unclear how Goh earned a living before he became a nursing student at the private school of about 100 students. In January, Goh was expelled. Oikos officials have not said publicly what led to his expulsion.
Jordan said that officials kicked Goh out for unspecified behavioral problems and that he had "anger management" issues.
People at the school "disrespected him, laughed at him," he said. "They made fun of his lack of English speaking skills. It made him feel isolated compared to the other students."
